Compound specific stable isotope determination of methylmercury in contaminated soil
Science of The Total Environment, 2018Rice is one of the main sources of methylmercury (MeHg) to humans, and soil is the main source of MeHg to rice grains. Determining the Hg isotope composition in environmental samples is a good way of characterizing sources of Hg pollution and investigating environmental processes.

Structure and Dynamics in a Bis(perfluoroalkyl)triazapentadiene Methylmercury Compound
Organometallics, 2004The compound [Ph2N3C2(C3F7)2]HgCH3 was synthesized from Na[Ph2N3C2(C3F7)2] and CH3HgCl. In solution, it exists as a mixture of two isomers that interconvert slowly on the NMR time scale. Both isomers feature a η1-Ph2N3C2(C3F7)2 ligand. In the asymmetrical one, the CH3Hg group is bonded to one of the two terminal nitrogen atoms.

Volatilization of mercury compounds by methylmercury-volatilizing bacteria in Minamata Bay sediment
Bulletin of Environmental Contamination and Toxicology, 1988Minamata Bay has been heavily polluted by high mercury concentrations which gave rise for a long time to methylmercury poisoning, Minamata disease (Kutsuna 1968; Irukayama 1977). The mercury still exists in the sediments of the Bay. The population of mercury-resistant bacteria in the sediments of Minamata Bay is larger than that in the sediments of ...

Preparation and structural studies of methylmercury compounds containing amino-deprotonated adenine
Inorganic Chemistry, 1986AbstractThe reactions of MeHgX (X: ‐OH, ‐NO3, ‐ClO4) with adenine in H2O/EtOH mixtures in different stoichiometric ratios give the compounds (I)‐(III) in a yield of about 60%.

Mercury-proton spin-spin coupling constants of some methylmercury compounds
Journal of Organometallic Chemistry, 1973Abstract The 199 Hg 1 H spin-spin coupling constants for methylmercury salts of 36 organic acids, CH 3 HgX (where X = OR − , SR − or OOCR − , were determined. A linear relationship between the coupling constants and the p K 's of the monobasic parent acids was found. The magnitudes of the coupling constants are dependent on the type of basic site,

Regeneration in two freshwater planarian species exposed to methylmercury compounds
Russian Journal of Developmental Biology, 2008The regeneration rate was studied by the morphometric method in planarians Polycelis tenuis and Dugesia lugubris after different periods of exposure on food substrates with high (0.30-0.50 mg/kg wet weight) and low (0.02-0.07 mg/kg) concentration of methylmercury compounds.

1H-NMR study of the removal of methylmercury from intact erythrocytes by sulfhydryl compounds
Journal of Inorganic Biochemistry, 1986The effectiveness of penicillamine, N-acetylpenicillamine, meso-2,3-dimercaptosuccinic acid, 2,3-dimercaptopropanesulfonic acid, and dithioerythritol for removing methylmercury (CH3Hg(II) from intact human erythrocytes has been studied by 1H-nuclear magnetic resonance spectroscopy.

Beans, cabbage, carrots, millet, onions, potatoes, and tomatoes were grown on silt loam, gravelly loam, and muck soils treated with 1 and 10 ppm of mercuric chloride, methylmercury dicyandiamide (PAN), or phenylmercuric acetate. Appreciable concentrations of methylmercury were present only in PAN-treated soils and in beans, millet and tomatoes grown on

The effects of natural methylmercury compounds on regeneration of photoreceptor organs were studied in three freshwater planarians: Polycelis tenuis, Dugesia lugubris, and D. tigrina. Accumulation of methyl mercury in the planarian body suppressed regeneration of P.
